WAVE Moron.`

Application med May 1, 19,25. sei-iai Naar/,250,

My invention relates to improvements .in Wave motors, and it consists in the combinations, constructions and arrangements here in described and claimed;

An object of the invention is the provision of a simple, reliable rand efficient de-g described which Will be positive in action andv is not likely to get out of order easily.V

Other objects andadvantages of the invention will be apparent from the following description, considered in conjunction with the accompanying drawing, in Which- Figure 1 is a side eleva-tion of my im proved' Wave motor. Y v

Figure 2 is asection substantially on the line2-2'of-Figure 1, and

Figure 3 is a section substantially along the line 3 3 of Figure 1'.

In rcarryingout the invention, I use of a substantiallyvertical obstruction 1 against which incoming Waves 2 impinge. The obstruction 1 maybe the face'of a cliff or of an embankment or other suitable struc-- ture. The supporting structure of the device includes a pair of spaced standards or columns 3 which are fixed to extend above the level of the waves in front of the obstruction 1. The horizontal supporting shaft or rod 4 extends between the upper end portions of the standards 3 and is supported by the latter to be substantially parallel to the plane of the obstruction 1. The standards 3 are stayed to the obstruction 1 by horizontal stay bars 5 having the inner end portions thereof secured tothe top of the obstruction 1 and the outer end portions thereof secured to the upper ends of the standards 3. p

The Vmotion transmitting mechanism of the motor comprising a pair of vert-ical# ly swingable arms 6 which are pivotally supported adjacent to their outer ends on the shaft 4f as best` seen in Figure 3 and are stayed to each other at their outer ends by a cross bar 7. The arms 6 carry an impact plate 8 Which hasthe lateral edge portions thereof secured on the arms 6 by rivets 9 or like fastening devices The plate 8 extends from the inner ends of the arms 6 to a level above the level of the waves 2 and both the inner end portion of the make plate 8 and the innerend portions of the arms 6 are curved downwardly substantially along the arc of afcii'cle as in i in Figure 1. The armsv and the plate 8 together form a pivoted lift member Which is swingable vertically iii response rto the force resulting from the impact of the incoming Waves Aagainst the under face of the iniierend portion of the lift member, the lift kmember being pivotally supported at its outer end andbeing inclined downwardly and inwardly toward its inner `end so that the inner end of the lift ineiiiberivill depend into the Water adjacent to the obstruction 1. rPhe 'arms G preferably are right anclearlyr gular iii cross sectionalcontour as shown in Figs. 2 and3. i A horizontal shaft 11 extends between the arms (3 adjacent to the inner ends these armsl and is supported by therarms 6. A

rack bai' 12 is'nivotally supported adjacent f to its loiver end on the shaft 11 and extends through an aperture 13 in the plate 8 above the `level vof the obstruction 1.4 pair of y13, being iixedly secured at rtheirupper ends to opposite sidesfof the rack bar 12, whereby `the rack bar Will be held inst movement axially of theA sha-ft 11 land is permitted to 19 which is mounted in aligned bearings 2O at the upper ends of vertical supports 21 on the obstruction 1. A fly Wheel22 is secured on ythe shaft 19 and may depend inl afrecess l0 or cavity 23 in the top of the obstruction. A bevel ring gear 23 maybe rigid with the fly Wheel 22 in concentric relation to the shaft 19 and in mesh with a smaller bevel gear 24 which is secured to a shaft 25. The latter is supported in a bearing 26 at the upper end of a support 27011 the obstruction and-may transmit motion to an air coin- `rockabout the axisy of the shaft 11 and lli) dotted line position in Figure 1 or towarc the dotted line position in Figure 1, thereby causing' upward movement of the racli bar l2 and imparting' a torque to the shaft 19 through the pinion 18. The invention contemp.

lvtes that there shall be very little 'fricthan ift any, between the rack b'ar and the pinion during the downward stroke ot' the rack bar and that the fly wheel 22 shall 'Function in conjunction with the pinion 1S to cause continuons rotation oi' the shaft 19 in one direction, the iy wheel functioning to cause rot-ation of the shaft 19 hiringthe down stroke oi' the rack bar. It desired, suitable known mechanism, such as a clutch between the pinion 18 and the shaft 19 may ne eu'iployed to positively disconnect the rack bar from the shaft 19 during' une downward stroke of the rack bar.

Obviously, the invention is susceptible o't embodiment in 'forms other than that which illustrated in the accompanying,r drawing, and l therefore consider as my own all such niodii'icatious and adaptations thereof as fairly tall within the scope of the appended claims.

l claim 1. A wave motor comprisinga supporting structure upstanding above the water in liront of an obstruction at the edge of a body of T(rater, a liftmember comprising a pair ot spaced arms pivotally supported at their outer ends on said supporting structure and depending inwardly and downwardly toward said obstruction, the inner ends of said arms being' iree to swingin an arc about the axial line of the pivotal supports of the outer ends of said arms, a litt plate secured on the inner end portions of said arms, a pinion rotatably supported on said obstruction7 a rack bar pivotally attached at its lower ends to said litt member and having teeth tor engaging;r with the teeth oit the pinion during` the upward stroke of the rack Vbar and for disengaging the teeth ot the pinion during` the downward stroke ot the rack har, the inner end portion of said plate and said supporting arms of the litt inember being' curved downwardly.

2. A wave motor comprising a supporting structure upsta-nding above the water in viront ot an obstruction at the edge of a body ot water. a litt member comprising a pair ol" spaced arms pivot-ally supported at their outer ends on said supportingstructure and depending' inwardly and downwardly toward said obstruction, a liftplate secured on the inner end portions of said arms, a pinion rotatably supported on said obstruction, a racl; bar nivotallv attached at its lower ends to said liit member and having teeth for engaging with the'teeth of the pinion duringthe upward stroke or' the rack bar and tor disengaging the teeth ot the. pinion during the downward stroke of the rack bar, the tace of said rack bar nearest to said obstruction and on which said teeth are provided being slightly convex in curvature 'trom its upper end to its lower end.
